Density Functions

Density functions are used in Minecraft world generation to define the shape and structure of terrain. They determine how different blocks are placed in the world, influencing features such as hills, valleys, caves, and other geological formations.

In Wyck, you can reference density functions that already exist in the game, are registered from datapacks, or author your own using the DensityFunction interface.

Tip

All built-in density functions are available in the DensityFunctions class, and any function registered from a datapack or external source can be referenced using DensityFunction.reference(ResourceKey).

Example Usage

ExamplePlugin.java Java Copy

import dev.wyck.keys.ResourceKey;
import dev.wyck.worldgen.noise.NoiseRouter;
import dev.wyck.worldgen.function.DensityFunction;
import dev.wyck.worldgen.function.DensityFunctions;
import org.bukkit.plugin.java.JavaPlugin;

public class ExamplePlugin extends JavaPlugin {
  @Override
  public void onEnable() {
      // Referencing existing density functions
      DensityFunction overworldRidges = DensityFunctions.RIDGES;
      DensityFunction datapackErosion = DensityFunction.reference(ResourceKey.of("test:my_erosion")); // or do it this way!

      // Authoring custom density functions
      DensityFunction customContinents = DensityFunction.yClampedGradient(0, 128, 1.0, -1.0)
          .add(DensityFunction.constant(0.05))
          .clamp(-1.0, 1.0);

      // Using the values in a noise router
      NoiseRouter router = NoiseRouter.builder()
          .continents(customContinents)
          .erosion(datapackErosion)
          .ridges(overworldRidges)
          .build();
  }
}
